About the NGA

NGA logo

The National Guideline Alliance (NGA) launched successfully on 1 April 2016, following a tender award by the National Institute for Health and Care Excellence (NICE) to the RCOG.

The NGA delivers the NICE contract as a multi-specialty guideline development centre, with a diverse topic portfolio across women and children’s health, mental health, cancer and social care.

The NGA represents significant growth in the RCOG as a knowledge organisation, working on behalf of other professions to develop robust, evidence based guidelines aimed at the continual improvement of patient care and services.

Since its inception, the NGA has expanded its portfolio through work with other organisations, providing training in aspects of guideline development, systematic reviewing and health economic analysis.

The NGA works with a number of partners, internally in the RCOG and externally with other organisations:


What we do

The NGA has over 50 staff across five business areas which collaborate in order to deliver commissions. Read about them below and see more about our services.

NGA staff also publish their work in peer-reviewed journals, conferences or other platforms. Here's a list of publications that NGA staff have contributed to.


NGA Leadership team

  • Gary Waltham, Executive Director
  • Vanessa Delgado Nunes, Senior Director
  • Angela Bennett, Director of Guidelines
  • James Gilbert, Head of Evidence Reviews


Guideline Leadership

The Guideline Leadership team oversee the development of each clinical and social care guideline produced by the NGA. Our Guideline Leads take overall responsibility for the delivery of the guideline, ensuring it provides all the required information and meets the defined standards set by the NGA and the commissioning organisations.

Our Guideline Leads also act as the main point of liaison between the commissioning organisations and those who contribute to the development of the guideline or work package, such as Guideline Committee members and other teams in the NGA.

Systematic Reviewing

Our Systematic Reviewing team summarise the clinical effectiveness of evidence as part of the evidence review, to help Guideline Committees decide which tests and treatments to recommend.

The first step in an evidence review is to create a review protocol that describes the type of evidence that will be looked for. Following the literature search being completed, our Systematic Reviewing team sift the search results to find relevant studies. The team analyse and summarise those results into an evidence report for the Guideline Committee, who use the evidence to make recommendations.

Our Systematic Reviewing team can also provide standalone evidence reviews and training on using GRADE methodology. 

Health Economics

Our Health Economics team undertake systematic reviews and quality appraisals of health economic literature to support the production of cost-effective recommendations in evidence based clinical and social care guidelines. They also develop new health economic models to assess cost-effectiveness where published evidence is lacking or not sufficiently up-to-date.

Health economists at the NGA can also provide advice and training on health economic concepts and methods.

Information Science

Our Information Science team undertake systematic literature searches for each clinical and social care guideline produced by the NGA.

Searching for the evidence is the first step in the guideline development process. The approach is methodological, transparent, and ensures reproducibility and adherence to best practice information and reporting standards:

  • First, scoping searches are undertaken to support the development of the guideline scope and the issues to be addressed.
  • Secondly, search protocols are developed and agreed with other members of the review team. These predefine how the evidence will be identified.
  • Finally search strategies are devised and systematic searches for the evidence are undertaken.

In accordance with other areas of information management, our Information Scientists document the search, manage references identified in the search, order papers, maintain clear audit trails of searches, and assist in the implementation of quality assurance processes and methods.

The Information Science team also offers a range of specialised information-based consultancy services. These include training on conducting literature searches, planning a proposal, scoping the literature, undertaking systematic searches and appraisals, quality assuring search methods, and documenting the search process to meet best practice reporting standards.

Project Management

Our Project Management team enable responsive planning to ensure that timelines and milestones are met, project risks are appropriately escalated and mitigated, and that resource allocation is supported throughout all project phases across the NGA’s projects. The team also ensure the NGA develops guidelines using best practice processes.

Business Management

The Business team support the Executive Director in the smooth running of the NGA’s business, communications and financial functions.
